An observed birth in a free living chimpanzee pan troglodytes schweinfurthii in gombe national park tanzania


, : An observed birth in a free living chimpanzee pan troglodytes schweinfurthii in gombe national park tanzania. Primates 21(4): 545-549

During 19 yr of study of chimpanzees in the Gombe National Park only one birth was observed; this is probably the first such observation for any chimpanzee in the natural habitat. The birth took place in a nest in a tall tree during the morning. Details were recorded by Tanzanian field staff from a neighboring tree. Labor, parturition and the mother's care of the infant immediately after birth are described. The mother consumed the placenta as she lay in another nest. Throughout the birth process the mother's juvenile son remained close by and watched with apparent interest. Another mother and her offspring were present during the birth and an adult male approached the mother while she was feeding on the placenta. Their behavior is described.
